Visual inspection

The X470 Master SLI is one of the affordable X470 chipset equipped motherboards on the market, featuring a black and grey color scheme similar with that of the Taichi motherboards. As with all motherboards that use the AMD Promontory X470 chipset, the Master SLI is compatible with all AMD Ryzen 1 and 2 CPUs from the factory. In addition, the motherboard features two M.2 storage ports and six SATA 3 connectors.


The X470 Master SLI features a Power delivery design using SM4336 and SM4337 MOSFETs which are both manufactured by Sino. The capacitors used are rated at 12,000Hours of operation and are manufactured by Nichicon.


The PWM regulator is manufactured by Intersil and is model number: ISL95712, capable of being programmable in 1, 2, 3 or 4-phases for the core output and 1, 2, 3-phase for the Northbridge output.

The power towards the CPU is sent through two connectors, a single 8 Pin and a single 4 Pin connector. While these two connectors can deliver power well above what any Ryzen CPU can use, these two connectors are installed on different layers of the PCB. This method is used to deliver a more stable current to the components of the board.


Both VRM heatsinks use an all-aluminum construction with a linear design and fins sculpted on both sides. Each heatsink is held in place over the VRM with two metallic screws each.


The motherboard features 4 (four) 4-pin Molex connectors, two are in close proximity to the CPU Socket and the other two are placed on the lower side of the motherboard next to the USB 2.0 and Aura header connectors.


The right side features four memory DIMM slots supporting a maximum of 64GB of DDR4 RAM. The rated speeds available are starting at 2133MHz and goes up to DDR4 3466+(OC), depending on the RAM kits installed and settings dialed in by the user.


Next to the DIMM slots there are two internal USB 3.0 headers alongside the 24Pin Power cable slot. Lower from these ports, there is a second Aura RGB connector installed.


The motherboard features two PCIe 3.0 x16 ports that are reinforced with metal to better support a heavy graphics card and aid in the reduction of Graphics Card sag.


Between the two PCIe 3.0 x16 slots we find the Bios chip alongside the Bios header, this chip is soldered on the PCB of the motherboard and thus is not removable.


Below the lowest PCIe 3.0 x16 slot and next to the Bios battery there is the Nuvuton NCT6779D Super I/O chip, that is responsible for the monitoring of most sensors of the motherboard.


The audio system has as its center point the Realtek ALC1220 codec while the capacitors used are made by Nichicon and are called Fine Gold. The whole audio system is covered by a plastic cover that blends in with the I/O cover. As is the case with all the new motherboards, the Audio system is separated from the rest of the components with the help of a LED illuminated line traced on both sides of the PCB.


The motherboard is equipped with two SATA M.2 slots for PCI-E NVMe M.2 SSDs, the first one is located below the CPU socket and features a preinstalled metallic heatsink. The second M.2 slot is placed below the Chipset heatsink right in front of the Bios battery.


The motherboard features six SATA3 6.0 Gb/s Connectors that will support RAID 0, RAID 1 and RAID 10.


On the backside, we have the I/O panel.
The I/O panel is as follows (from left to right):
– 1x PS/2 Mouse/Keyboard Port
– 1x HDMI Port
– 1x Optical SPDIF Out Port
– 1x USB 3.1 Gen2 Type-A Port (10 Gb/s) (Supports ESD Protection)
– 1x USB 3.1 Gen2 Type-C Port (10 Gb/s) (Supports ESD Protection)
– 6x USB 3.1 Gen1 Ports (Supports ESD Protection)
– 1x RJ-45 LAN Port with LED (ACT/LINK LED and SPEED LED)
– HD Audio Jacks: Rear Speaker / Central / Bass / Line in / Front Speaker / Microphone



The bios utilizes a simple interface, although most motherboards today use two Bios modes, the first one being the EZ Mode destined for casual users and the second being the in depth Bios meant for power users. The Master SLI just like other ASRock motherboards does not offer an EZ (Eazy) mode bios for beginners. The bios for this motherboard uses a black and silver theme inspired by the overall design of the motherboard.



The following system was used to test the motherboard:
– CPU: AMD Ryzen 1700X @ 3.6GHz
– RAM: Ballistix Tactical Tracer 16GB DDR4 @ 2666MHz
– GPU: Nvidia GeForce GTX 1070 Founder’s Edition
– HDD: WD 1TB Blue
– SSD: Samsung 840 EVO 120GB
– PSU: Seasonic Snow Silent 750W Platinum
– CPU Cooler: Noctua NH-L9x65 SE-AM4
– Case: Phanteks Enthoo Luxe
– OS: Windows 10 64-Bit (After April Update)


The processor was used with the stock turbo frequency of 3.6 GHz and overclocked to 4 GHz with a core voltage of 1.355. The overclocking starts at 3.8 GHz and with each motherboard I try to achieve the highest safe overclocking possible.
The RAM memory was used at its default frequency


Software used for testing the motherboard:

– 3D Mark – FireStrike, CloudGate, IceStorm.
– CineBench r11.5
– SuperPi mod 1.5
– wPrime v1.55
– Grand Theft Auto V
– Deus Ex Mankind Divided
– The Witcher 3: Wild Hunt

Final thoughts

The ASRock X470 Master SLI is part of the affordable segment of X470 equipped motherboards, however it does offer plenty of features and overclocking headroom. This particular motherboard managed to overclock the Ryzen 1700X to 4.0 GHz at a core voltage of 1.4V.
The bios of the motherboard however has some lacking features including the beginner or EZ (easy) bios front page, while the X470 chipset is meant for overclocking and thus generally used by experienced users, the EZ Bios offers a quick way to change the general settings.
The performance of the motherboard is good, the Ryzen 1700X CPU being able to reach a frequency of 4.0GHz with a core voltage of 1.4V while the dual channel memory kit was able to hit 3200MHz with ease.

Although there has been a wide discussion regarding the VRM used in the case of the X470 Master SLI, during all the testing done with this board, both gaming and benchmarks, there were no voltage spikes or VRM overheating. The monitoring was done with HWiNFO v5.90 and the latest version of Aida 64 Extreme Edition as well as with two external temperature probes.

In conclusion, the ASRock X470 Master SLI is an affordable motherboard that offers the X470 chipset and a couple of needed features such as two SATA M.2 slots, metal reinforced PCIe 3.0 x16 slots and 12K rated Nichicon Black Caps. In terms of design, the board also features full RGB illumination and two LED strip headers, alongside a black and grey color scheme.

    It will be appreciated if you can provide the best setting for this motherboard to reach max cpu speed on ryzen 2700x. Thanks

    • May 8, 2019 at 8:48 am

      What settings are you interested in? Memory frequency and timings or Overclocking the 2700X?

      • May 12, 2019 at 11:21 am

        Stock cooler 2700x max speeds either manual oc or xfr2. what do you currently getting only up to 4150mhz speed on 1core and 3925mhz on all cores using auto setting and xfr2 enabled.

        • May 12, 2019 at 11:29 am

          Stop using the Auto functions, first of all. The memory frequency, make sure it’s running in XMP mode by default.
          Set the CPU core ratio for all cores at 40.00, this will lock all cores at 4.0GHz. This is your baseline, you first, get all the cores at 4.0GHz and then try to see what is the lowest voltage the CPU will be stable at 4.0Ghz. Only afterwards, you try to go above 4.0GHz.

    Is there a good stable overclock for a ryzen 3600x with G skill Trident RGB 3200mhz.

    • June 11, 2020 at 10:57 pm

      Depends on the quality of the CPU and what frequency you are aiming for.
